      The conversion of biomasses from agriculture into either hydrogen or chemicals is a target of primary importance for sustainable development. In their Full Paper on page 851, Claudio Bianchini and co-workers report a method to produce both hydrogen and chemicals in a single process making use of electricity provided by renewable energy sources. The cover image shows an effectively assembled self-sustainable hydrogen fuel cell; hydrogen is produced by the electrolysis of aqueous solutions of alcohols. The realization of such a process will provide ultrapure hydrogen and, at the same time, lead to the sustainable production of industrially relevant feedstocks from biomasses.

    1. Simultaneous Aqueous-Phase Reforming and KOH Carbonation to Produce COx-Free Hydrogen in a Single Reactor (pages 803–806)

      Jun Liu, Xianwen Chu, Lingjun Zhu, Jiye Hu, Rui Dai, Songhai Xie, Yan Pei, Shirun Yan, Minghua Qiao and Kangnian Fan

      Article first published online: 11 JUN 2010 | DOI: 10.1002/cssc.201000093

      Thumbnail image of graphical abstract

      KOH is Key: A one-pot multistep approach is developed for the production of COx-free H2 from biomass-derived oxygenates. By using KOH as process modifier, a gas product containing exclusively 97 % of H2 and 3 % of methane is obtained from aqueous-phase reforming of ethylene glycol in a single reactor over an unmodified non-precious-metal catalyst. This approach enables the production of H2 in an energy-efficient and cost-effective manner.

    2. Effective Gasoline Production Strategies by Catalytic Cracking of Rapeseed Vegetable Oil in Refinery Conditions (pages 807–810)

      T. V. Malleswara Rao , M. Milagrosa Clavero and Michiel Makkee

      Article first published online: 22 JUN 2010 | DOI: 10.1002/cssc.201000128

      Thumbnail image of graphical abstract

      The incorporation of nickel onto a commercial FCC catalyst and co-feeding H2 into the reaction system improves the catalytic performance of rapeseed oil cracking, with respect to gasoline and light olefins (propene and butenes) production. On the other hand, the incorporation of platinum, with or without co-feeding of H2, is detrimental to both the conversion and the selectivity. Thus, a judicious choice of metal is vital for performance during vegetable oil cracking.

    3. A Direct, Biomass-Based Synthesis of Benzoic Acid: Formic Acid-Mediated Deoxygenation of the Glucose-Derived Materials Quinic Acid and Shikimic Acid (pages 811–813)

      Elena Arceo, Jonathan A. Ellman and Robert G. Bergman

      Article first published online: 28 MAY 2010 | DOI: 10.1002/cssc.201000111

      Thumbnail image of graphical abstract

      Shikimic Gimmick: An alternative biomass-based route to benzoic acid from the renewable starting materials quinic acid and shikimic acid is described. Benzoic acid is obtained selectively using a highly efficient, one-step formic acid-mediated deoxygenation method.

    4. A Spinel Oxynitride with Visible-Light Photocatalytic Activity (pages 814–817)

      Venkata Bharat Ram Boppana, Douglas J. Doren and Raul F. Lobo

      Article first published online: 11 JUN 2010 | DOI: 10.1002/cssc.201000036

      Thumbnail image of graphical abstract

      Spinel zinc gallium oxynitride photocatalysts are prepared by the sol–gel method, at 550 °C. In these materials, of base composition ZnGa2O4 (octahedral Ga), reaction with ammonia leads to ZnGa2OxNy, with a dramatic reduction of the bandgap to 2.7 eV, with just 1.3 % N and no loss of Zn. At 850 °C this phase is converted into wurzite (tetrahedral Ga). The novel oxynitrides also show visible-light photocatalytic activity towards the degradation of methylene blue.

    5. Selective Transformation of Cellulose into Sorbitol by Using a Bifunctional Nickel Phosphide Catalyst (pages 818–821)

      Li-Ning Ding, Ai-Qin Wang, Ming-Yuan Zheng and Tao Zhang

      Article first published online: 21 MAY 2010 | DOI: 10.1002/cssc.201000092

      Thumbnail image of graphical abstract

      Biomass conversion over a nickel phosphide catalyst is explored for the first time. Through both acid and metallic sites on the Ni2P catalyst surface, cellulose is selectively transformed into sorbitol in yields as high as 48.4 % and at sorbitol/mannitol ratios as high as 10:1. The results are superior to results achieved by using precious-metal catalysts, which can be attributed to the efficient “cooperation” between the two types of active sites.

      Methanolics anodymous: The anodic oxidation of 1,3-diisopropylbenzene in methanol leads to the bis-methoxylated intermediate which can be converted under acidic conditions in appropriate alcohols into the corresponding bis-alkoxylated products.

    2. New Method for H2S Removal in Acid Solutions (pages 829–833)

      Alberto de Angelis, Giuseppe Bellussi, Paolo Pollesel and Carlo Perego

      Article first published online: 16 JUN 2010 | DOI: 10.1002/cssc.201000010

      Thumbnail image of graphical abstract

      A new H2S conversion method based on acid ferric nitrate solution, co-catalyzed by a heteropolyacid is developed. H2S is converted to pure sulfur (S>99.9 %), with no traces of organic compounds. Due the acid pH of the solution no chelant, to prevent metal sulfide precipitation, or surfactant is needed and iron content in the solution can reach a very high level (up to 0.6 mol L−1 and more).

    3. Alkyne Hydroarylation in Ionic Liquids Catalyzed by Palladium(II) Complexes (pages 834–839)

      Article first published online: 9 JUL 2010 | DOI: 10.1002/cssc.201000039

      Thumbnail image of graphical abstract

      Ionic liquids with noncoordinating anions are found to greatly affect the performance of palladium(II) complex catalysts for alkyne hydroarylation. Suitable anions are found to significantly improve the catalytic performance in comparison to homogeneous conditions. Preliminary investigations on the recyclability of the system as well as on the advantages of using an acidic ionic liquid are also carried out.

    4. Carbon Dioxide Capture on Amine-Rich Carbonaceous Materials Derived from Glucose (pages 840–845)

      Article first published online: 23 JUN 2010 | DOI: 10.1002/cssc.201000044

      Amino Royale: The synthesis of carbonaceous materials with a high surface density of amino functions for CO2 sorption and sequestration is reported. The biomass-based materials show significant sorption capabilities for CO2 (4.3 mmol g−1at −20 °C and 1 bar).

    5. Metallic Plate Corrosion and Uptake of Corrosion Products by Nafion in Polymer Electrolyte Membrane Fuel Cells (pages 846–850)

      Benedetto Bozzini, Alessandra Gianoncelli, Burkhard Kaulich, Maya Kiskinova, Mauro Prasciolu and Ivonne Sgura

      Article first published online: 16 JUN 2010 | DOI: 10.1002/cssc.201000048

      Thumbnail image of graphical abstract

      Contamination of fuel-cell membranes with metal ions, resulting from the use of ferrous alloys, leads to corrosion and ultimately failure of the device. By using a combination of X-ray spectroscopy techniques, the corrosion processes of Ni and Fe electrodes in contact with a hydrated Nafion film are investigated. The results show diffusion of corrosion products within the film only in the case of the Fe electrodes, whereas Ni electrodes appear corrosion resistant.

    6. Self-Sustainable Production of Hydrogen, Chemicals, and Energy from Renewable Alcohols by Electrocatalysis (pages 851–855)

      Valentina Bambagioni, Manuela Bevilacqua, Claudio Bianchini, Jonathan Filippi, Alessandro Lavacchi, Andrea Marchionni, Francesco Vizza and Pei Kang Shen

      Article first published online: 22 JUN 2010 | DOI: 10.1002/cssc.201000103

      Thumbnail image of graphical abstract

      Ultrapure hydrogen is produced in an alkaline polymeric membrane electrolyzer through selectively oxidation of a renewable alcohol to the corresponding carboxylate at the anode. The low amount of energy required for this reaction, about one-third the energy required by a traditional water electrolyzer, allows the electrolyzer to be self-sustainable when combined with a hydrogen fuel cell.
